I laughed because you are right, but you're heavily discounting the fact that most people would cowtow immediately if they thought they could get the slightest bit of protection.

I mean, the sales pitch works to get them to buy the guns. After that point whatever they do with them is no longer the salesperson's concern... :-P

The same goes with prepper gear - like, what amount of food & water is going to help you survive a nuclear winter? Especially in comparison to paying taxes to a government that will formulate economic strategies that lead towards nations never using such weapons in the first place, b/c their wealthiest business-people stand too much to lose.

I can barely imagine the mindset of a prepper who readies themselves for all manner of attacks against them... but then refuses to take a vaccine? Or wear a mask, or simply stand 6 feet apart and/or reduce going out especially during peak times, and also works to prevent others from having access to those vaccines or wearing masks of their own volition.

Some people are more vulnerable to different types of "attacks", disinformation being one of the most effective that has ever existed.:-(

wolverines!

18th century artillery? I suppose it also depends on whether we were talking a squad, platoon, etc., whether the single person has to defend a particular area like their home with family inside, whether this whole army was in one place, whether the army intentionally traveled through time vs. simply were teleported there against their will (in which case they likely could be convinced to surrender, especially upon seeing a helicopter - and like, wherever they came from were they a defensively minded unit, like would their morale be crushed to realize that neither victory nor defeat would ever allow them to see their loved ones again - plus these defenders could literally be their own family members as in descendants), etc.

But without going into such details, my point was they technology has advanced quite a bit since the 18th century, which would give someone with a modern gun a decided advantage for them to make use of.
